Nintendo World Championship cartridge was original made for the "Nintendo World Championship" Nintendo held across the USA in 1990. Special cartridges were made that included three games on them (Super Mario Bros, Rad Racer, and Tetris). You had a limited amount of time to get the most points possible on all three games.
Only 26 of these cartridges were released to the public. The age group winner in each host city received a cartridge as their prize.
It's considered one of the rarest and most expensive video games ever.
